DRlP-TROUGH FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 566,209, dated August 18, 1896.. Application filed May 11, 1896. Serial No. 590,974. (No model.)

To all whom it may concern.-

Be it known that I, JOHN C. MILLER, of Vaterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Drip-Troughs for Central- Draft Lamps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a view in side elevation of a central-draft tube provided with a drip-trough constructed and applied in accordance with my invention 5 Fig. 2, a view thereof in vertical central section; Fig. 3, a detached view of the trough in side elevation; Fig. 4:, a plan View thereof; Fig. 5, a reverse plan view thereof.

My invention relates to an improvement in drip-troughs for central-draft lamps, the object being to provide simple and effective means for preventing such lamps from weeping, as the term is.

IVith these ends in view my invention consists in the combination, witha central drafttube made short of the full length of such tubes, of an annular U-shaped drip-trough adapted to receive an air-distributer and discharge the oil intercepted by it, and superposed upon and secured to the upper end of the said tube, which it completes to full length.

My invention further consists in the combination, with a central draft-tube made short of the full length of such tubes and having its upper end turned inward to form a supporting-flange, of an annular U -shaped drip trough having its inner and outer walls and bottom formed entirely independent of the said central draft-tube, adapted at its upper end to receive an air-distributer, having its lower end perforated for the discharge of the oil intercepted by it, corresponding in exterior diameter to the exterior diameter of the drafttube, having its lower end supported upon the flange thereof and secured by an oil-tight joint to the said tube, which it completes to full length.

In carrying out my invention as herein shown I form an inwardly-extending annular horizontal supporting-flange A at the upper end of the central draft-tube A, which is made short of the full length of such tubes. Upon the said flange I support an annular U-shaped drip-trough B, having its inner and outer walls and bottom formed entirely independent of the said draft-tube, adapted at its open upper end to receive an air-distributer C, which may be of any approved construction, and having its lower end formed with perforations I) for the discharge of the oil intercepted by it. The said drip-trough is supported, as before explained, upon the flange A, an oil-tight joint between the bottom of the trough and the flange being formed by a band of solder D, which firmly attaches the trough to the draft-tube. The trough corresponds in exterior diameter to the exterior diameter of the draft-tube, of which it forms an extension and the full length of which it completes, for, as has been before stated, the draft-tube properis in itself short of full length.

By making the draft tube short of full length I effect an economy of metal. The supporting-flange also aifords a simple, cheap, and effective way of applying the drip-trough.

t is apparent that in carrying out my invention some changes from the construction herein shown and described may be made, and I would therefore have it understood that I do not limit myself to the particular form set forth, but hold myself at liberty to make such changes and alterations therefrom as fairly fall within the spirit and scope of my invention.

I do not in this application broadly claim an annular U-shaped drip-trough having its inner and outer walls and bottom formed entirely independent of the central draft-tube to which it is applied, adapted at its upper end to receive an air-distributer, and having its lower end perforated for the discharge of the oil intercepted by it, inasmuch as Ihave claimed that subject-matter in an application filed November 25, 1895, Serial No. 570,072, and allowed April 23, 1806.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a central drafttube made short of the full length of such tubes, of an annular U-shaped drip-trough, adapted to receive an air-distributer, and discharge the oil intercepted by it, and superposed upon and secured to the upper end of the said tube which it completes to full length.

2. The combination with a central drafttube made short of the full length of such tubes, and having its upper end turned 111- Ward to form a supporting-flange, of an annular U shaped drip-trough, having its inner and outer Walls and bottom formed entirely independent of the said central draft-tube, adapted at its upper end to receive an air-
